Airalo has the biggest catalog. travel.to has the cleaner buying flow + an honest refund policy.
Airalo is the largest eSIM marketplace by country coverage but the UX optimizes for picking through hundreds of carrier-branded plans. travel.to abstracts that: one unlimited plan per trip length, picked for you.
How the two compare on what matters.
Why travel.to over Airalo.
-
1
One plan per trip length instead of fifteen, so there is nothing to compare.
-
2
Refund policy codified on the home page, not buried in support docs.
-
3
Country pages designed for working travelers (carriers, speed band, timezone, roaming gap) rather than vacationers.
-
4
Faster path from "I need an eSIM for Spain" to a working eSIM (one search, one click, one email).
